The day President Kennedy was assassinated there were urgent messages exchanged between the air force command centre and the White House.
These new tapes, uncovered from the personal effects of General Chester Clifton Junior, a military aid to JFK, reveal the historic moment when news of the assassination was reported.
One recording states, 'Wayside, this is situation Room. I read from the AP bulletin. Kennedy apparently shot in head, he fell facedown in the backseat of his car. Blood was on his head. Mrs Kennedy cried 'Oh No' and tried to hold up his head.'
They also include a rare glimpse into personal moments, such as then vice-president Lyndon B. Johnson expressing his condolences to JFK's mother.
Forensic audio and video expert Ed Primo has been tasked with remastering and piecing together the tapes.
'It's spine tingling,' he says. 'We’re hearing several commanders communicating logistical information about interrupting everybody’s plans because the President was assassinated and about what it’s going to take to get them to all come together and deal with this disaster.’
